Due to the non-affine form of the control inputs, feedback linearization method can not be used to design control system. Therefore, implicit function theorem is firstly exploited to assert the existence of the ideal control inputs, which can compel the system outputs to track their desired trajectories, and then ideal control inputs are constructed.

由于该系统的控制输入为非仿射形式，不能采用反馈线性化的方法设计控制系统；因此，首先采用隐函数定理证实了能够使系统输出跟踪期望轨迹的理想控制输入的存在性，并构造了理想的控制输入。

The application of reflected optical difference system in surface crack of aluminum detection is also discussed. By analyzing the experimental data, we found that the reflected pulsed wave techniques could be used to measure the position of crack precisely and depth imprecisely. Transmitted wave contain much size information of the crack, despite without position information. The spectrum of transmitted is sensitive to the depth of crack. The deeper the crack is, the narrower the spectrum bandwidth is.

使用自建的光偏转差分检测系统，对铝样品中多种表面缺陷进行了检测，对表面波直达波，反射波，透射波波形及频谱进行了分析，讨论超声表面波与各种缺陷相互作用后的变化，通过对实验结果的分析，发现缺陷脉冲发射法可以精确测定缺陷位置，粗略估计缺陷深度；而透射法测的波形无法定出缺陷位置，但包含了缺陷大小信息，透射波频谱对缺陷深度非常敏感，随缺陷深度的加深，频谱不断的左移。

A donor's sperm can be used to impregnate five women, according to the Ministry of health.

从国家卫生部得知，捐献者的一个精子能够使五位妇女受孕。

At the same time, we discussed the fittable field of deep convective impressible model comparing with the origional pressible equations.The result is that deep convective impressible model is close to the pressible model and is good to be used to simulate troposphere.

本文首先对中小尺度动力学进行理论探讨，特别是与本文有关的深对流不可压动力学模型，比较它与原始可压运动方程组的联系及其适用范围，表明在对流层的研究中使用浅对流不可压模型是不可行的。

This mouse models can be used to examine the efficacy and safety of novel treatment strategies to prevent or reduce CNS impairments as well. In first of all, we established inbreed transgenic stains of human mutant apoE and related disease models.

该模型的建立不仅可从整体水平上研究apoE基因的多种功能，也为相关疾病的病因学和功能基因的研究，以及评价新的治疗或预防措施的效果和安全性提供了理想的手段。

The sampling frequency can be used to formulate an appropriate plan in order to avoid the blindness and incertitude.

用该方法计算的水质采样频率，可为制定水质监测方案提供参考依据，避免制定水质监测方法的盲目性和不确定性。

For example, if we need a list that will be used to keep track of project progress then the content type for this should include the columns like Project, task, responsibility, status etc. Content types provide the means to encapsulate a data schema and make it independent of a location on a SharePoint site.

例如，如果我们需要一个将用于跟踪项目进展情况跟踪那么这应该包括项目，任务，责任，地位等内容类型的列的内容类型列表提供手段来封装数据模式，使它独立于一在SharePoint网站上的位置。
